Halo Reach multiplayer not accessible on some XBox 360 systems

Were you one of the thousands who waited up until midnight to pick up Halo Reach for the Xbox 360? Well, some of you may have gotten a nasty little surprise when you got home if you own the 4GB model of the Xbox 360 Slim. According to reports, multiplayer doesn't work on these consoles due to the 4GB model having a "Memory Unit" instead of a hard drive.

Apparently Halo Reach will give you a "hard drive is required" message if you attempt to play any co-op modes like campaign or firefight. Although it is not listed on the packaging, Microsoft has been quoted on the issue stating "some multiplayer aspects of Halo: Reach require an Xbox 360 certified hard drive." Seriously? The only fix at this point is to buy a $130 USD Xbox 360 Slim hard disk. So much for getting a deal on the $199 Slim console.
